The given variable is a continuous variable.

<h3>What is continuous variable?</h3>

A quantitative variable can be either continuous or discrete depending on whether it is normally obtained through measurement or counting. A variable is continuous over a range of real values if it can take on any two specific real values and all other real values in between.

<h3>What is mercury thermometer?</h3>

In Amsterdam, physicist Daniel Gabriel Fahrenheit created the mercury thermometer, also known as a mercury-in-glass thermometer. It consists of a glass tube with a small diameter and a mercury bulb attached to it; the bulb contains far more mercury than the tube does.

<h3>According to the information:</h3>

A mercury thermometer was used to take the subject's temperature.

Because of the temperature:

  • Not counting but measuring it.
  • You can use a decimal number to represent its value.
  • As a result, it is open to any value inside an interval.
  • Temperature is therefore a continuous variable.
  • The only format in which discrete values can be stated is as whole numbers.

so

Temperature is a continuous variable,

If u want u can answer question 14 and 15 but if u don’t just answer 14
natali 33 [55]

Answer:

For #14, (around) 108 times.

#15 = 53

Step-by-step explanation:

14)

2.69*10^5 = 269000

2.5*10^3 = 2500

269000/2500 = 107.6

Rounding up, we get 108

15)

√(53 - 8)2 + (31 - 3)2

= √(45)2 + (28)2

= √2809

= 53

This rectangular prism is intersected by a plane that contains points B, D, H, and F.
tankabanditka [31]

Answer:

The perimeter of the cross section is 33.3 cm

Step-by-step explanation:

Given: A rectangular prism with height 6 centimeters, length 8 centimeters, and width 7 centimeters. The rectangular prism is intersected by a plane that contains points B, D, H, and F.

We have to determine the perimeter of the cross section.

Since, The plane is drawn diagonally such that it intersect the points  B, D, H, and F.(as shown in figure below)

Perimeter of a figure is the sum of its outer boundaries.

We first find the length of diagonal HF.

Since, HGFE , is a rectangle

So, Diagonal of rectangle is given by

D=\sqrt{Length^2+breadth^2}

Here, Length = 8 cm

and breadth = 7 cm

So, D=\sqrt{8^2+7^2}=\sqrt{64+49}\approx 10.63

Thus, HF = DB = 10.63 cm

Therefore, Perimeter of cross section is DB + BF +FH + DH

= 10.63 + 6 + 6 + 10.63 = 33.26

Thus, the perimeter of the cross section is 33.3 cm
